Available in multiple sizes and various bottom designs, with full support for custom specifications. This allows for precise tailoring to fit specific furnace dimensions, material types, and unique processing requirements.
Application Scenario
Laboratory & Scientific Research
Crucial for a broad range of scientific experiments in chemistry, physics, and materials science, providing a non-reactive and heat-resistant container for samples during thermal decomposition, ash content determination, and other high-temperature analytical procedures.
Handle with care
Quartz glass products are made from valuable materials and must be handled gently to avoid collisions and falls.
Regular maintenance
The maintenance of quartz tubes must be performed regularly to ensure their long-term stable performance. Regularly check the connections, fixings, and mechanical vibrations of the quartz tubes to prevent abnormalities. The exterior of the quartz tubes is prone to contamination from dust and moisture, so they should be cleaned regularly.
Storage environmen
When storing quartz tubes, care should be taken to avoid exposure to mechanical vibrations, shocks, and excessively high temperatures. They should be kept in a dry, cool, and well-ventilated place, avoiding direct sunlight and high-temperature environments.
Absolutely. Our quartz boats are highly customizable. We offer various standard sizes, but we specialize in tailor-made solutions. You can specify exact lengths, widths, heights, bottom designs (e.g., flat, round, grooved), and even the shape of the single handle to perfectly match your furnace, sample layout, and unique process requirements.
These high-purity quartz boats are designed for excellent performance at high temperatures, capable of sustained use up to 1200°C, making them suitable for demanding processes like metal smelting. Regarding chemical compatibility, they are highly resistant to most acids and alkalis. However, they are generally not resistant to hydrofluoric acid (HF) or hot phosphoric acid.
Quartz boats are ideal for high-purity applications due to their exceptional material properties. Made from SiO2 with ≥ 99.99% purity, they are non-contaminating, ensuring that no impurities leach into your samples during high-temperature processing. Their smooth, bubble-free surface further prevents particle generation, which is critical for sensitive processes like wafer handling in semiconductor manufacturing, maintaining product integrity and yield.
